Introduction.The HCV infection is a common disease with many chronically infected patients worldwide. So far, the standard therapy of a chronic HCV infection consisted of interferon as single therapy or in combination with ribavirin. After approval of the two protease inhibitors, boceprevir and telaprevir, the standard therapy for patients with genotype 1 changed. In patients with acute kidney injury (AKI) these therapies are not approved and have so far not been evaluated in studies.Case Report.In April 2012, a 58-year-old female was admitted due to a cryoglobulin-positive chronic HCV infection which had been treated with interferon and ribavirin. Currently, the patient was admitted because of severe complications with an acute kidney injury. We treated our patient successfully with a boceprevir based triple therapy.Conclusion.Limited data suggests that a therapy with ribavirin in patients with AKI seems to be safe under close monitoring. Our patient was treated successfully with a protease inhibitor based triple therapy. Nevertheless, it is necessary to plan an interventional study to evaluate the exact risk-benefit profile of triple therapy regimens in patients with AKI and hepatitis C.

Chronic Hcv

Hepatitis C virus (HCV) infection results in not only chronic hepatitis and subsequent complications as liver cirrhosis and hepatocellular carcinoma, but also in a significant number of other diseases, the so-called extrahepatic manifestations of chronic HCV infection. This is because of viral hepatotropicity and lymphotropicity. The most striking example of the course of chronic HCV infection, in which the infectious and inflammatory processes are concurrent with autoimmune disorders and carcinogenesis, is mixed cryoglobulinemia and B-cell non-Hodgkin’s lymphoma. The pathogenesis of these diseases is based on the clonal expansion of B cells, which occurs under their prolonged stimulation with the virus or viral proteins. Part 1 of this review is devoted to the analysis of a correlation of chronic HCV infection with lymphoproliferative and autoimmune disorders, as well as its association with kidney injury.

Direct Acting

Background Coadministration of direct-acting antivirals (DAAs) for chronic hepatitis C virus (HCV) infection and first generation anticonvulsants is currently not recommended due to a drug-drug interaction that could potentially lead to subtherapeutic DAA levels and subsequent treatment failure. Currently, there is limited data evaluating this interaction and timely treatment of HCV infection with DAAs is imperative to prevent liver-related morbidity and mortality. Methods A retrospective case series evaluating clinical cure of chronic HCV infection, defined as sustained virologic response (SVR) 12 weeks after completion of DAA therapy, in patients from three inner-city clinics who remained on first generation anticonvulsants during the treatment course. Results A total of five patients received standard dose DAAs for treatment of chronic HCV infection while being maintained on first generation anticonvulsants. The most common HCV genotype was 1a (80%), followed by 1b (20%). The majority of patients were treated with glecaprevir/pibrentasvir (80%) for eight weeks and one patient was treated with ledipasvir/sofosbuvir for 12 weeks. Anticonvulsant regimens consisted of carbamazepine, phenytoin, phenytoin plus phenobarbital, phenytoin plus levetiracetam, and phenobarbital plus lacosamide. All five patients achieved sustained virologic response (SVR) despite this drug-drug interaction. Conclusion Although every effort to prevent concomitant use of DAAs and potent inducers should be made, clinical cure may still be achieved in patients whom cannot avoid this coadministration.

Infection with hepatitis C virus (HCV) imposes a global challenge with over 180 million cases worldwide. Only few patients spontaneously had their virus neutralized, while most patients develop chronic HCV infection. This implies a key role of genetic factors in viral clearance or persistence. The current study aimed at clarifying the effect of certain single nucleotide polymorphisms (SNPs) on individual's susceptibility to HCV infection.  A total of 60 patients with confirmed HCV infection and 35 apparently healthy individuals were enrolled in this study. Blood sample was obtained from each participant, from which DNA was extracted. The JAK1gene was amplified with conventional PCR technique using three sets of primers targeting three SNPs in this gene: rs2780895, rs4244165 and rs17127024. Restriction fragment length polymorphism (RFLP) was used for genotyping of PCR products. Each of rs2780895 and rs17127024 had two genotypes in both patients and controls, however, only the heterozygous genotype of the SNP rs2780895 (CT) significantly associated with the susceptibility to HCV. The SNP rs4244165 appeared in only with homozygous wild genotype (GG) in both patients and controls. It can be concluded that allele T of the SNP rs2780895 could be considered as a risk factor for infection with HCV

Abstract Background Hepatitis C virus (HCV) elimination by 2030, as targeted by the World Health Organization (WHO), requires that 90% of people with chronic infection be diagnosed and 80% treated. We estimated the cascade of care (CoC) for chronic HCV infection in mainland France in 2011 and 2016, before and after the introduction of direct-acting antivirals (DAAs). Methods The numbers of people (1) with chronic HCV infection, (2) aware of their infection, (3) receiving care for HCV and (4) on antiviral treatment, were estimated for 2011 and 2016. Estimates for 1) and 2) were based on modelling studies for 2011 and on a virological sub-study nested in a national cross-sectional survey among the general population for 2016. Estimates for 3) and 4) were made using the National Health Data System. Results Between 2011 and 2016, the number of people with chronic HCV infection decreased by 31%, from 192,700 (95% Credibility interval: 150,900-246,100) to 133,500 (95% Confidence interval: 56,900-312,600). The proportion of people aware of their infection rose from 57.7 to 80.6%. The number of people receiving care for HCV increased by 22.5% (representing 25.7% of those infected in 2016), while the number of people on treatment increased by 24.6% (representing 12.1% of those infected in 2016). Conclusions This study suggests that DAAs substantially impact CoC. However, access to care and treatment for infected people remained insufficient in 2016. Updating CoC estimates will help to assess the impact of new measures implemented since 2016 as part of the goal to eliminate HCV.

BACKGROUND/OBJECTIVE: Liver biopsy has been the gold standard for grading and staging chronic hepatitis C virus (HCV)-mediated liver injury. Traditionally, this has been performed by trained practitioners using a nonimage-guided percutaneous technique at the bedside. Recent literature suggests an expanding role for radiologists in obtaining biopsies using an ultrasound (US)-guided technique. The present study was undertaken study to determine if the two techniques produced liver biopsy specimens of similar quality and hypothesized that at our institution, non-US-guided percutaneous liver biopsies for HCV would be of higher quality than US-guided specimens.METHODS: Liver biopsies from 100 patients with chronic HCV infection (50 consecutive US-guided and 50 consecutive non-US-guided), were retrospectively identified using a hospital histopathology database. All original biopsy slides were coded and prospectively reanalyzed by a single hepatopathologist who was blinded to the technique used in obtaining the biopsy. Additionally, all liver biopsies for chronic HCV infection completed at the centre from 1998 to 2007 were identified and the technique used was recorded. Biopsy quality was determined primarily by the number of complete portal tracts (CPTs) identifiable in the slides. The total length of specimen and the degree of fragmentation were secondary outcome measures.RESULTS: There was a slight difference observed between the US-guided and non-US-guided groups in mean age (46.3 years versus 42.5 years, repectively; P=0.018) but no differences in sex, presence of cirrhosis, bilirubin, creatinine, international normalized ratio, and grade or stage of disease. Biopsies obtained using the US-guided technique produced higher quality specimens than the non-US-guided technique based on our primary outcome of number of CPTs in the biopsy (11.8 versus 7.4; P<0.001). US-guided specimens also were longer (24.4 mm versus 19.7 mm; P=0.001), had less fragmentation (P=0.016), and a higher overall histopathological quality assessment (P=0.026) than the non-US-guided biopsies. However, there was no significant difference between the two groups in the ability to grade and stage the disease (96% US-guided versus 90% in non-US-guided (P=0.20). Over a 10-year period, 763 biopsies for chronic HCV infection were identified with an obvious trend toward the increased use of US-guided technique observed at 2% in 1998 to 85% in 2007.CONCLUSIONS: US-guided liver biopsies for chronic HCV are the most common method of obtaining specimens at the Kingston General Hospital, Kingston, Ontario, and are of higher quality than non-US-guided specimens. However, there is no significant difference in the two techniques in the ability to grade and stage chronic HCV.
